I think Kishimoto has been stupid trolling us like that. He gave us lots of NaruSaku hints/parallels throught the whole manga and then, boom, nothing in the end. Kishimoto gave more or less 6 NaruHina hints in the whole manga & it happened anyway. That just hurts too much. No sense. Sakura seemed over Sasuke and boom in 693-700 chapters she’s magically back into him. Not to speak of Sasuke that in the last chapter in 5 minutes falls for Sakura. Before he tried to kill her, he didn’t care about her at all, called her annoying etc. That is just nonsense.
People can say Sakura may always loved Sasuke from the start & Naruto accepted it but Sasuke never showed love or even care toward her. Only in the end he did. That’s pretty rushed. You don’t fall in love so fast. Before he even tried to kill her and now he loves her. Plus Sakura referred to Sasuke as her lover with the past tense in the chapter where Sasuke uses the jutsu on her to make her faint. So she was over him but then at the end she changed her mind again, nonsense to me. All her development got wasted & shattered.
also the fact that Sakura faked a smile when Sasuke was back in the war shows she didn't love him, Sai even thought so as well. Minato’s words about Sakura being Naruto's girlfriend and being alike to Kushina got wasted. Kushina herself wished for Naruto to find a girlfriend alike her and Sakura acts alike Kushina.
About Naruhina: They had too little scenes together in the whole manga. He supported her in the Chunin exam and he avenged her loss vs Neji but at that time he still had feelings for Sakura so he didn’t do it for love. One time Naruto said he liked Hinata though she was a weird girl. People could consider that a confession from him but it’s not because he still kept showing his on his crush on Sakura. One time Hinata protected Naruto from Pain and she confessed her love for him and he didn’t answer anything. People could say it was because there was a war and the time wasn’t right to confess back to her but even when it was over he didn’t speak to her. One time they held hands during the war vs Obito and she touched him on the face. That's it? Is it enough to say they are in love? After the war he stood next to her during Neji’s funeral without saying a word and years later they have kids??!! Kishimoto should have developed more SasuSaku and Naruhina relationship so it would have had more sense to have them canon instead of wasting time on NaruSaku that didn’t even happen.
